They can not ban the mining in there, because it would be killing the whole industry and i guess that a lot of people will be against that. It would be like a revolution for the whole miners in there.. and of course that neo is not going to replace that, because it is not even mineable, there is no way to get neo by mining them, so it means that the miners will be going to burn all those rigs because there is nothing profitable to mine at the moment. Well, mining ico's tokens is not a good deal, but honestly, i dont think that it is going to happen.
